Adjusting data structure?

I'd imagine that it's because we're trying to set through a getter function. I can't be more specific as I don't use Zend GData.

Find what variable getVideoId() sets, and see if you can alter that directory, (if it's not private). Be warned, however, your library may not take kindly to that level of tinkering. I'd image that the ID should be numeric, or some other specific format, and probably shouldn't contain any HTML.
